The following example will show you how to convert an InputStream to String. Hey ti is very easy process to do this. Just go through this code line by line and try to understand each steps.

package org.kodejava.example.io;
 
import java.io.InputStream;
import java.io.IOException;
import java.io.BufferedReader;
import java.io.InputStreamReader;
 
public class inputStreamToString {
 
    public static void main(String[] args) throws Exception {
        inputStreamToString ists = new inputStreamToString();
 
        
        InputStream ists = iists.getClass().getResourceAsStream("/data.txt");
 
        System.out.println(sts.convertinputStreamToString(ists));
    }
 
    public String convertinputStreamToString(InputStream ists) throws IOException {
       
        if (ists != null) {
            StringBuilder sb = new StringBuilder();
            String line;
 
            try {
                BufferedReader r1 = new BufferedReader(new InputStreamReader(ists, "UTF-8"));
                while ((line = r1.readLine()) != null) {
                    sb1.append(line).append("\n");
                }
            } finally {
                ists.close();
            }
            return sb1.toString();
        } else {       
            return "";

Hey it is very easy process to convert InputStream to String in java. I have just written one example to convert InputStream to String in java. Just try to under stand each steps.

public static String inputStreamAsString(InputStream stream)
throws IOException {
BufferedReader BR = new BufferedReader(new InputStreamReader(stream1));
StringBuilder SB = new StringBuilder();
String line1 = null;

while ((line1 = BR.readLine()) != null) {
SB.append(line1 + "\n");
}

BR.close();
return SB.toString();
}

You can easily convert InputStream to String in java. You have to just take input from user and using following program you can convert InputStream to String. I think following example will clear you concept about converting InputStream to String.

      public static String pop (InputStream in) 
     throws IOException {
    StringBuffer put = new StringBuffer();
    byte[] B = new byte[5069];
    for (int N; (N = in.read(B)) != -1;) {
        put.append(new String(B, 0, N));
    }
    return put.toString();
}

I had written following code for converting InputStream to String in java and it is working properly in my pc. Just try to understand this code and try to compile in your computer.

public String parseISToString(java.io.InputStream ips)
{
java.io.DataInputStream di1 = new java.io.DataInputStream(ips);
StringBuffer sb = new StringBuffer();
try{
String line = null;
while((line=di1.readLine()) != null){
sbw.append(line+"\n");
}
}catch(Exception exw){
ex.getMessage();
}finally{
try{
ips.close();
}catch(Exception exw){}
}
return sbw.toString();
}
